Description

Multi-level stereoscopic image display device and method

Technical field

The present invention provides a multi-level stereoscopic image display device and method, and more particularly, a method for utilizing a primary image display member and at least one light transmissive display member to enable a primary image and at least one primary image Overlapping to form a device and method with multi-level effect stereoscopic images.

Background technique

Television has always been an indispensable electronic product in people's family life. With the development of technology, in addition to the continuous improvement of image color and resolution to provide more natural and realistic image quality, the development of 3D stereoscopic display is also provided. People's further visual senses, in addition to the general image and color, provide a sense of three-dimensional space. The human brain can take advantage of binocular parallax (Binocular Parallax), to determine the sense of distance of the object. These stereoscopic sensations provide humans with higher reliability in interpreting image information. Therefore, with the rapid development of display technology, the application of stereoscopic image displays has become more diversified. Its main classification is divided into the following items:

(1) Glasses-type 3D imaging technology

1. Red and blue (green) glasses (Anaglyph): as early as the 1850s Joseph D'Almeida It is the use of red and green glasses to play stereoscopic movies, causing a sensation. This is to draw the images of the left and right eyes in the same picture in different colors. When wearing red and blue glasses, using the principle of color filtering, the left and right eyes can see images with different angles. But the downside is that you can only see grayscale or single-tone images, and can't provide more natural and realistic image quality.

2. Polarized glasses (Polarizing Glasses): The application of polarized glasses is one of the more popular technologies. Horizontal and vertical polarized lenses are used on the left and right eyes of the glasses. This allows only horizontally polarized light to be seen at a glance, while the other eye can only see vertically polarized light. The imaging device simultaneously projects horizontal and vertical light for viewing to the left and right eyes. However, the disadvantage is that when the head is slightly inclined, the polarized glasses often cannot completely filter out the light in the other direction. The eye will see the image of the other eye, and some viewers will feel uncomfortable.

3. Shutter glasses (Shutter Glasses): When the image is played, the image device divides the image into odd images and even images. The setting of the odd image is accepted by the right eye, and the shutter glasses cover the left eye for viewing by the right eye. Then put the even image on the same principle, so you can see the stereo image alternately. The glasses themselves are made of liquid crystal, so that the left and right eyes can be controlled to open and close. But the disadvantage is that the glasses cost more and require additional power. Moreover, since the frequency difference between the eyes of the shutter glasses is easy to flicker, it is also easy to cause additional flickering due to the flicker frequency of the fluorescent lamp and the synchronization speed error between the shutter glasses and the television picture.

(2) Naked 3D image technology

1. E-holographic: mainly developed by the Massachusetts Institute of Technology, using red, blue, and green laser light sources, each passing through an acousto-optic modulator crystal (Acoustic Optical) Modulator, AOM), produces a phase-type grating, and the laser light with the raster information is combined by the full image, using a vertical scanning mirror (Vertical Scanning) Mirror) and polygon mirror (Polygonal Mirror), vertical and horizontal scanning, and then the stereoscopic image is presented. The advantage is that the hologram is easy to obtain and mature. However, the image size is often limited by the size of the acousto-optic modulator crystal, and the polygon mirror The scanning speed must be synchronized with the three-color laser source at the crystal propagation speed.

2. Volumetric: Texas Instruments (Texas Instrument, TI) proposes a laser-scanning stereoscopic image display, which is also known as a volumetric display. As shown in Fig. 4, mainly by using a fast rotating disc, with the laser light source projected from the bottom, when the laser light source is projected onto the rapidly rotating rotating surface, a scattering effect is generated to scan each space. One disadvantage is that there must be a rotating axis in the center of the image. The image near the axis rotates slowly and the stereo image is less clear.

technical problem

However, the technology of the aforementioned 3D stereoscopic display mostly requires special processing of the film through the front, and in combination with a special display device, a high technical threshold is required, which causes difficulty in technology popularization.
